Most wallet comparisons are written by the wallet. You can tell, because the conclusion is always the same. This one has the same problem, so here is the bias stated up front: we built nimimo, we think it is good at something specific, and we think there are situations where you should use a hardware wallet instead.
The useful question is not which wallet is best. It is what each category is actually optimizing for, because they are not optimizing for the same thing.
Exchange accounts
An account on an exchange optimizes for recoverability and trading. Forget your password and you can get back in. That is a genuine feature, and for people who have lost seed phrases it is the difference between an inconvenience and a permanent loss.
The cost is that recoverability and custody are the same mechanism. The exchange can restore your access because it controls the keys, which means it can also freeze them, lose them, or be compelled to hand them over. You are holding a claim on funds, not the funds.
For an amount you would be annoyed but not damaged to lose, and for active trading, that trade is often reasonable. For savings, it is the trade that has gone wrong most often in this industry's short history.
Hardware wallets
A hardware wallet optimizes for keeping the key away from the internet. The secret is generated on a dedicated device, signing happens on that device, and a compromised computer sees a signature rather than a key. For large balances held long-term, nothing else in consumer crypto is as good at this.
The cost is friction on every axis that is not security. There is a device to buy, a seed phrase to write down and physically protect, firmware to keep current, and a multi-step ritual for every transaction. Receiving means finding the device, connecting it, selecting the chain, and reading an address off a small screen.
None of that is bad design. It is the price of the guarantee. But it means the hardware wallet is a poor fit for the case where someone wants to send you forty euros right now and neither of you wants a ceremony.
Browser extension wallets
Extensions optimize for interacting with applications. If you are using on-chain apps regularly, an extension is the right shape. It is there when a site needs it, it signs when you approve, it stays out of the way otherwise.
They tend to be chain-family shaped, so people accumulate several. And the seed phrase problem remains yours: twelve or twenty-four words you are responsible for, with the same permanence and the same consequences for losing them.
Where nimimo fits
nimimo optimizes for being paid. Specifically, for the case where someone who is not a crypto person wants to send you something, on whichever chain they already hold, without either of you installing anything.
You get one name that resolves to Bitcoin, Ethereum and Solana addresses. You put the link in a bio or an invoice. The sender opens it, picks the chain they have, and sends from whatever wallet they already use. They do not need a nimimo account, an app, or an explanation.
Underneath, the model is the same non-custodial one: the wallet secret is generated in your browser, encrypted with a key the browser will not let any page read, and never transmitted. The server holds your email, your handle and your public addresses. Nothing that could move funds.
The seed phrase is still there, in the sense that a BIP-39 mnemonic exists. What changes is that you are not asked to manage it by hand. The recovery path is a PDF with a PIN-encrypted QR code, restorable offline on any device.
Where nimimo is the wrong tool
We would rather say this than have you find out later.
- Life-changing sums held long-term. A browser is a larger attack surface than a dedicated signing device. Use hardware.
- Heavy on-chain application use. An extension is built for that interaction pattern and nimimo is not.
- You want an institution that can restore your access. That is custody, and it is a legitimate thing to want. We structurally cannot provide it.
- You need chains we do not support. One name is only useful across the chains it covers.
The honest failure mode: clear your browser data with no recovery card and the wallet is gone. There is no reset, because there is nothing on our side to reset from. Make the recovery card when prompted; it takes under a minute and it is the entire safety net.
These are not mutually exclusive
The framing where you pick one wallet and that is your wallet does not match how people actually hold crypto. A hardware wallet for savings, an extension for applications, and a public handle for receiving are three different jobs, and using all three is not indecision.
What nimimo replaces is not your hardware wallet. It is the part where you paste a forty-character address into a chat and then send a follow-up message asking the other person to check the first four characters.
